Mine would have to be Toy Story 2.
One of the Tomba games or Resident Evil 2/3. Digimon world was awesome too.

crash team racing
Syphon Filter 
Tomba!
Metal Gear Solid.
Rage Racer, Crash Bandicoot 2 or 3. Maybe Steel Reign : P
Getting me nostalgic now, games I used to play as a kid -_-
gta 2 or crash bandicoot or twisted metal
Resident Evil 1-3
Silent Hill
No one could beat me at resident evil, fucking no one. I beat that shit in 49 minutes, no saves, no deaths, all characters saved. First try too.
Sorry for the brag but, those were the fucking days…
LSD
tripped me out…
I had a N64 :3
every kid that had a Nintendo ended up as a furry with negligent parents
I never had a ps1 but I am gonna say metal gear would be the best from what I have seen
Xenogears FTW
medievil
Oh shit I forgot that game, it was the shit.
And whats wrong with N64? It kicked ass playing SSB, OOT, and Majora’s Mask among other games.
Final Fantasy IX. Or VII.
I don’t know.
Resident evil 3 and Parasite Eve 2.
Spyro the Dragon, Medievil, Legend of Kane: Soul Reaver (still waiting for the next part in this series), Lara Croft: Tomb Raider (pyramid shaped boobs ftw. Not really.), Mortal Kombat, and Soul Edge.
